Hello @Fie ,

I think your request to automatically deduct discounts from a new order or invoice based on whether prior invoices were paid on time will require business events and possibly customization. 

In standard Credit Terms screen and in Sales Prices screen, we don’t have options to take discount based on credit standing, or # days before due the customer’s  last invoice was paid, etc. (We can’t just check a box to accomplish your request.)

It may be possible to create a Business Event to change the customer’s price class based on  whether invoices are past due.
